Power adapter manufacturers teach you how to contribute to environmental protection?

Low-carbon life, start from a small thing!
The big desk on the computer desk is full of sockets. Each time the lights go
off, there's always a power adapter that lights up on a dark desktop. Are you
used to unplug the unused power adapter, have you ever thought of these idle
power adapter consume energy in vain?

Power adapter (power adapter) is a small
portable electronic devices and electronic power supply power conversion
equipment, generally composed by the shell, transformers, inductors,
capacitors, control IC, PCB board and other components, its working principle
from AC input to DC Output; According to the connection can be divided into
wall-mounted and desktop. Widely supporting in security cameras, set-top boxes,
routers, light bar, massage devices and other equipment. You might think that power adapters such as cell phones and
digital cameras consume only a few watts of power even when working, let alone
stand by. But I saw a power adapter total energy meter, the number really
surprised me. Cell phone charging power consumes about 4W, power adapter
standby power consumption 0.5W (really not much smaller than the light bulb). A
typical user may charge up to 7 hours a week, and the adapter will wait 161
hours without unplugging the power adapter. Accounting to the annual, cell
phone charging will consume 1.456 kW.h, while standby will consume 4.186 kW.h.
According to the current price of 0.48 yuan per kilowatt-hour, each power
adapter is busy for one year and the ineffective standby consumes you 2 dollars
more. But from a global perspective, these inefficiencies are a staggering
figure. In 2009, the global handset sales volume was about 1.21 billion units.
If 10% of users do not use the power adapter, it will consume 500 million
kilowatt-hours annually, or about 240 million yuan. If you add digital cameras,
MP3 / MP4, camcorders, laptops, etc. A bunch of power adapters that are always
plugged into the patch panel, or 10% estimate, the total standby power
consumption will reach about 1 billion degrees ! 100 million kw.h electricity! The 1 billion kilowatt-hours
of electricity is enough to support the electricity consumption of about 1
million typical Chinese households, which, if converted to carbon emissions,
will add 7.85 million tons of carbon dioxide and require about 8.2 million
trees to absorb. However, these are just the tip of the iceberg. The standby
power consumption of TVs, DVD players, set-top boxes and other products is usually
less than 1W, and very few people have the habit of completely turning off the
power of these audio-visual products, most of which are used to shut down
standby mode.

Support low-carbon life, start from a small
thing, the home wiring board are replaced with a switch, to develop the habit
of turning off the power at any time.
